A micro-analysis of the helium and neon contents of air.

Effect of Low–Level Helium-Neon Laser Irradiation on the Release of Interleukin 6 and Basic Fibroblast Growth Factor from Cultured Human Fibroblasts in High Glucose Medium

Purpose: Low level laser therapy is suggested as a new therapeutic method in diabetic wound healing. This survey aimed to evaluate the effects of low level laser on human fibroblasts cultured in high glucose cultures. Materials and Methods: The human skin fibroblasts were cultured under standard condition. The cells were cultured in high glucose culture medium (15mM/L) for a week and two weeks ...

Photobiological Effects of 2 mw Helium Neon Laser with 632.8 nm Wavelength on Albumin, Total Protein and Activity of LDH, CPK, ALP in Blood

Effect of Helium-Neon Laser Irradiation on Motility and Ultrastructure of Fresh and Frozen-Thawed Human Sperm

Purpose: Semen freezing is an important technique in human infertility treatment in many different patients but it damages sperms. Low-power lasers are physical agents that have biostimulatory effects. In this study, low-power helium-neon laser's (16J/cm2, one time irradiation) effect on motility and ultrastructure of fresh and frozen-thawed human sperm were studied. Materials and Methods: Thi...

Effect of Low-Power Helium-Neon Laser Irradiation on Collagen Fibril Thickness of Incisized Medial Collateral Ligament of Knee in Rat

Purpose: The aim of the present study is to investigate the effect of low-power Helium-Neon laser (LPL) on collagen fibril thickness of incisized medial collateral ligament of knee joint (MCL) in rat. Materials and Methods: MCL of right hind limb of 35 male adult sprague Dawley rat under general anesthesia were transversly incisized. Rats were randomly divitded into normal, control, first lase...

Effect of Helium-Neon Laser and Sodium Hypochlorite on Calf Thymus Double-Stranded Deoxyribonucleic Acid Molecule: An in Vitro Experimental Study

Introduction: Low-energy helium-neon (He-Ne) laser beam lightis used in combination with sodium hypochlorite (Na2HOCl3) for clinical purposes. Regarding this, the present study aimed to investigate the effect of He-Ne laser (632.8 nm) and sodium hypochlorite on the calf thymus double-stranded deoxyribonucleic acid (ctdsDNA) molecule.  Materials and Methods: For the purpose of the study, ctdsDNA...
